The girl was abducted around 3 a.m. Wednesday and found about 12 hours later wandering near a Starbucks several miles away. She was barefoot, had bruises and scratches, and wasn’t wearing the same clothes she had on when she vanished.

Police on Sunday arrested Daniel Martinez, 29, in Northridge and booked him for investigation of kidnapping in connection with the case. He was being held on $1 million bail.

Authorities continue to search for a second suspect, Tobias Dustin Summers, who may have changed his appearance by shaving his head. He is considered armed and dangerous, Los Angeles police said.

A Los Angeles police spokeswoman would not say Monday why authorities believe Summers, a transient with a long criminal history, is in San Diego. He was identified by authorities over the weekend as a suspect in the kidnapping case.

Police initially said they were looking for two suspects but noted they were focusing their efforts on Summers. A possible connection between Summers and Martinez wasn’t immediately clear.

Investigators have said they believe the girl was driven around the San Fernando Valley in a couple of cars and taken to at least two locations, including a storage facility, before she was released.

The Los Angeles Times reported that law enforcement sources said the girl was sexually assaulted.

Police noted Summers had a criminal history dating back to 2002 and had been arrested for robbery, grand theft auto, possession of explosives and kidnapping.

Authorities haven’t given a motive for the kidnapping. They don’t believe Summers and the family knew one another.

Summers was described as white, 6 feet tall, and about 160 pounds. He has a large tattoo on his upper right arm.

Anyone who spots Summers was asked to call 911 immediately.

Tipsters with information about Summers were urged to contact the department’s Robbery Homicide Division tip line at (213) 486-6890.
